APERAK Application error and acknowledgement message (D19A)

This is the standard EDIFACT D19A spec, with 5 loops and 17 segment positions, as OpenEDI JSON, an ediFabric C# template and an ediFabric Native model. To change it for a trading partner, customize it in the EDI Spec Builder.

Use the APERAK spec in your code

ediFabric .NET

Add the C# template and its common files to your project, or reference the template NuGet package, and read APERAK files into TSAPERAK objects. See ediFabric .NET.

ediFabric Native

Native supports X12 today, and EDIFACT is coming. When it's available, map version D19A to this Native model with set_map to parse APERAK files to JSON from Python, Java, C or C#. See ediFabric Native.

OpenEDI

Select Customize in Spec Builder to copy the spec under your own name, change it for your partner, and parse files against it in EdiNation, ediFabric Native or ediFabric Cloud. Read about OpenEDI.

Generate APERAK classes in Python, Java, Node.js, Go, Rust or C

The OpenEDI file describes each APERAK as JSON. To work with APERAK data as typed objects, generate classes from the OpenEDI file in your language; the root class is TSAPERAK. The classes keep the loops, segments, lengths and code lists, but not the EDI data formats. Read more in Generate a class from OpenEDI.
